UNITED STATES PATENT DANIEL SEGUR, OF TOLEDO, OHIO.

REGESTER FOR ELEVATORS, 34G.

Application filed October 15, 1885.

To all whom, it may concern:

' Be it known that I, DANIEL SEGUR, ofToledo, in the county of Lucas and State of Ohio, have invented a new and Improved Register ing-Machine, of which the following is a full, clear, and exact description.

The object of my invention is to measure and register the distance traveled by hydraulic elevators in one direction, which distance being known the consumption of water can be calculated when the size of the cylinder or piston attached to the elevator is known.

To the end stated, my invention consists of the combination of parts, including their construction, which will be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similarletters of referenceimlicate corresponding parts in all the figures.

Figure 1 is a view of the register-actuating mechanism, the main clutch being indicated in dotted lines, and the cover of the countingcase being removed. Fig. 2 is a sectional view of the actuating mechanism, taken on line at w of Fig. 1., the registering clock -work, however, not being shown in section, and Fig. 3 is a view of the grooved and recessed hub or disk of the main clutch.

In order to measure the amount of water used by a hydraulic elevator it is necessary to know how far the piston has traveled in one direction, and this information may be obtained by the use of such an apparatus as I have illustrated, and will hereinafter describe. In order to measure the travel of the piston in one direction it is only necessary to register the distance through which the elevator itself is moved, and the proportional travel being known the desired result is easily ob tained; but to be accurate, the registering mechanism must be actuated only when the elevator is moving in one direction and held against any possible retrograde movement when the direction is reversed, and it is to obtain this end that I have invented the actuat ing mechanism illustrated in the drawings, wherein- A represents a hub or disk, which is rigidly afiixed to or made integral with a short shaft,

a, one end of said shaft being stepped or fitted FICATION forming part of Letters Patent No. 336,756, dated February 23, 1886.

in bearings formed in the back plate, I), of the casing B, while the other end of the shaft pro jects through and is guided by a casting, C, which is secured within the casing B by screwbolts 0 c c", which engage with threaded sockets formed in bosses, which project from the side walls of the case I The casting C is provided with a horizontal arm, m, the func tion of which will be seen further on. A sprocket-wheel, D, is loosely mounted on the shaft a, the wheel being so formed that its web revolves in close proximity to the cast ing 0, while its toothed rim d, the inner face of which is circular, projects backward over the peripheral face 6 of the hub A. The face 6 of the hub A is formed with a number of recesses or pockcts,ff, above whiclnat the points 9 g, the hub closely approaches the rim d of the sprocket-wheel D; but below the pockets the face 0 is grooved, as shown at hin Fig. 2, the grooves running about as indicated by dotted lines in Fig. 3. In each of the recessesf there is an iron or other hard-metal ball, such as those shown at 7; It.

The end of the shaft (0 which projects through the casting G, carries a grooved wheel, N, which is fast upon the shaft, and a pinion, 0, also fast upon the shaft, said pinion being arranged to engage with the main driving-wheel O, ofa clock-work registering mechanism of any of the well-known constructions, such as that shown at K, said registering mechanism being secured to the casting G by means of screws which engage with threaded sockets formed in posts ZZ, as shown, the whole mechanism described being inclosed by a cover, E, having a glass face, F, through which the dials of the registering mechanism are visible.

Upon the casting C there are cast two curved ridges, a a, which approach but are not concentric with the grooved wheel N, clamping-balls i i being placed between the ridges and said wheel, so that although the wheel N will be free to turn in the direction of the arrow, it cannot turn in the opposite direction.

The casing B is formed with two ridgesmp, and the cover E with two corresponding ridges, q q, the two sets of ridges facing, as shown in Fig. 2, to form a way or groove for the passage ZOO of the driving-chain M. The casing is completed by a wall, 1, which projects outward and abuts against the cover E.

In operation the sprocket-wheel D is driven by achain, M, which runs the full length of the shaft, and is arranged to be adjusted by suitable means, as by a screw and swivel joint. When the device is operated by a direct or vertical elevator or piston, the arm m of the casting 0 will be in about a horizontal line. Then as the elevator is started upward the chain M will be moved in the direction of the arrow shown in connection therewith, which movement of the chain M will cause the wheel D to revolve in the direction of its arrow, and the balls k It will bind between the rim d and the face 6 of the hub A, thereby moving the shafta and its pinion o in the direction desired to impart a forward move ment to the registering mechanism. When the elevator is started downward,the direction of the travel of the chain M will be reversed, as will also that of the wheel D, and it now becomes important that the registering mechanism should be held in place and not be at fected by the reverse movement of the wheel D, and this holding of the registering mechanism is secured by means of the act-ion of the wheel N, balls 1' or i, and ridge n or n, for when the device has been set up, as described, and the arm min a horizontal position, as shown in the drawings, the moment the wheel N stops revolving in the direction of its arrow the ball z will drop down between the ridge n and the wheel and prevent the turning of the wheel in an opposite direction, as

will be clearly seen from the construction illustrated in Fig. 1. These parts-that is, the wheel N and ridges and balls arranged in connection therewith-are only designed as a safety attachment, as under ordinary circumstances the hub A would not be moved when the wheel D was revolved in a direction opposed to that indicated by the arrow, as the balls It would have nothing to bind against;

esnse but should the hub be started by accident,as', say,by friction, the balls tor 13 would at once check the retrograde movement.

When the device is attached to a compound elevator wherein a horizontal piston is used, the position would be such that the arm m would be vertical.

Although I have described myinvention as operating in connection with an elevator, it will of course be understood that it is equally applicable to any machine where it is necessary to move the registering mechanism in one direction, but to hold it against any retrograde movement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a' registering machine, the toothed wheel having a rearward or lateral rim, the hub having recesses and grooves carrying balls, the axis or shaft of said hub carrying at its one end a wheel, in combination with the eccentric ridge or ridges, and additional ball or balls interposed between said latter wheel and ridge, substantially as and for the purpose set forth.

2. In a registering-machine, the chain engaging the toothed wheel having the lateral or rearward rim, the hub having the recesses and grooves carrying the balls, the axis or shaft of said hub carrying at its one end a wheel, in combination with the eccentric ridge or ridges, and the additional ball or balls interposed between said ridge and the latter wheel, and the registering'mechanism geared to the said shaft or axis, substantially as and for the purpose set forth.

3. The combination, with a friction-clutch, substantially as described, a toothed wheel and a chain, of a case formed with ridgespp', and a cover having ridges q q, substantially as described.
